Banzhaf cites the opinions by Judge Barry Williams in the cases of the three officers acquitted so far, including the Rice case, where Williams ruled that the state had not presented evidence to show criminal liability on the part of Rice.

In all three cases where the officers were acquitted, Williams stressed several points in his decision including:

- Failing to follow general police orders are not necessarily a crime, especially when that violation happened due to poor judgment rather than due to someone acting in a grossly negligent manner.

- The state failed to prove when Gray's fatal injuries occurred during his time in the police transport van.

- Prosecutors could not prove the defendants were aware of the new police policy that required officers to seat belt arrestees and took away discretion to do so. Given that, the officers had discretion on whether to seat belt Gray given their concerns over his behavior and the crowd at the time of his arrest.

Despite consistently ruling for acquittal, Williams has opted to allow the individual officers' cases to move forward, saying that prosecutors offered enough evidence for the indictments to hold up in court.

Banzhaf says the prosecutors' actions violated the Maryland Lawyer's Rules of Professional Conduct and the U.S. Constitution.

"They could not have reasonably believed that the charges were supported by probable cause, and would support a criminal conviction, at the time they were issued, much less after the judge repeatedly ruled that there was literally 'no evidence' to support vital elements of the charges," the complaints state.

The allegations raised are the same as those raised against in a complaint filed by Banzhaf against Mosby that prosecutors deliberately withheld evidence from defense attorneys and that prosecutors continued a case that a prosecution should proceed only if there is sufficient and admissible evidence to support a conviction.

Mosby's office is barred from commenting due to a gag order put in place by Williams regarding the Gray cases.

The complaint comes as Officer Garrett Miller is set to go on trial July 27. He is charged with second-degree assault, misconduct in office and reckless endangerment.

Miller testified in Nero's trial that he is the one who physically arrested Gray after Rice called in for a pursuit of him. However, that testimony came under the promise of limited immunity meaning that testimony cannot be used against him in his trial.

Therefore, Schatzow and Bledsoe will not be prosecuting that case, or the retrial of Porter in September. Porter testified for the state in the Rice trial. Assistant state's attorneys Lisa Phelps and Sarah David will lead the prosecution in the Miller and Porter trials.

A number of defense attorneys and many in law enforcement who have been watching this case have called on Mosby to drop the remaining cases.

"It is time to end this witch hunt that State's Attorney Mosby has been leading," said Chuck Canterbury, national president of the Fraternal Order of Police said in a statement. "She has disgraced her office and there should be charges of prosecutorial misconduct brought against her immediately."

Fraternal Order of Police Lodge 3 President Gene Ryan repeated that call to Mosby.

"We again strongly urge Mosby to stop he malicious prosecution against the three remaining officers," Ryan said in a statement. "Based upon the evidence presented in the previous trials, we are certain the remaining three officers will also be found not guilty. The manner in which the first four cases have been presented, the citizens of Baltimore should be very concerned."

Also on Monday during a stop in Montgomery County, Gov. Larry Hogan told The Washington Post that the remaining charges should be dropped.

"It's a waste of time and money," Hogan told the newspaper, adding "but that's up to the court system to decide."
